    摘要: A process for inducing alignment of a liquid crystal medium adjacent to a surface of an optical alignment layer comprising: exposing at least one optical alignment layer to polarized light; the polarized light having a wavelength within the absorption band of said optical alignment layer; wherein the exposed alignment layer induces alignment of the liquid crystal medium at an angle + and -.theta. with respect to the direction of the polarization of the incident light beam and along the surface of the optical alignment layer; and applying a liquid crystal medium to the optical alignment layer, wherein the optical alignment layer is a polyimide comprising an an amine component having a 2-substituted 1,4-benzenediamine wherein the 2-substituent X.sub.1 is an electron withdrawing group having a positive .sigma.. Also claimed is a liquid crystal display element made by the process.

    摘要: The present invention provides novel hybrid polymer useful for alignment layers for inducing alignment of a liquid crystal medium. Hybrid polymers of this invention are prepared from at least one component selected from the group consisting of monomer, oligomer and polymer within the class of polyimides, poly(amic acids) and esters thereof and at least one component selected from the group consisting of addition monomer and functionalized addition polymer wherein the two components are covalently bonded to form a copolymer. The invention further describes liquid crystal optical elements such as all liquid crystal display products or modes, liquid crystal devices and liquid crystal optical films comprising the novel hybrid polymer alignment layers.
